DUMP 1303s' MINE CARS. e

Application ledAugust 14, 1924. Serial No. 732,115.

This invention relates to improvements in dumps, and more particularly to dumpsfor coalminecars,- andthe objects of the invention are to provide an efficient and economically constructed and automatic device of thisv kind' with no complicatedv parts and which will, in operation, give more satisfactory vresults than similar devices heretofore in use. V f

lfurther objects are to provide a dump in which, after `thecar is dumped, .it is auto# rmatically elevated to the return track.A

With the foregoing and-'other objects in view, theY inventionA consists essentially in the combination and arrangementofparts hereinafter more vvfully described;

Referring now to thel drawings, in which like characters ofreference indicate corresponding parts in each figure:

Figure l is a side elevation.

Figure 2 is a top'plan'view.

Figure 3 is an endz elevation.

A designates the'dump as a whole Vcomprising a trackssupporting*frame B and a tilt'able' carriage @adapted to 4carry a loaded car and to travel in the track-carrying frame. The frameBcomprises'a rectangularisteel or iront base lOonwhich'a-re mounted a plurality ofluprights lldesignedfto support the inclined gui-de'ways ortracks l2 and 18 in which thewheels 11i oflthecarriage C are adapted to travel. The frameB is suitably re-enforced by cross-bars 15 and a lengitudi'nallyv extending bar 16, the whole being designed to .form a horizontally eX- tendingf skeleton'supporting frame'l? with inclined tracks thereon onV which, aspreviouslymentioned, a .carriage C is adapted to travel upwardly and downwardly.

This Vcarriage is of substantiz'rllyY wellknown construction and is adaptedto sup- VY port a platform 18 tiltably mountedthereon at 19 by means of a shaft20 and provided with tracks or rails 2lv and 22 rof goosenecked formation at their outer ends so that kwhen the car is pushedand the wheels fun up against the bent endI of the railsthe car is pastithe centre which vallows it to tipl forward, it should be, further noted that the rails 21 and A22 are 'slightlyinclined to the horizontal, the purposey of'which will be hereinaftery more fully referred to.

The car Dis of :the usual construction and p 'matlcally drops to its normal position; as

is provided witha'swingingly mounted Vend `gear on the shaft-2T.

door 2Oa on which are the hook members 23 and 24, while'on the carriage 1s mounted an angle iron frame 25 extending outwardly Vand upwardly in slantwisey direction thereor other content to run out asimore particu larlyillustratedv in Figure 3.`

The mechanism for operating thecarriage comprises a transversely extending shaft'27 suitably j ournaled in the head portion o-ffthe frame. On this shaft is mounted 'a gear 28 and also a sprocket 29, while'parallel'to this driving shaft 27 is 'the' shaft 30 on "which is a smaller gear 3l adaptedto mesh with the gear 28,' andl on the'otl'ier end a larger gear 32 adapted to mesh with the smaller Also on the shaft 2T is a friction clutch 33 whereby the shaft 27 is driven to in turnl operate the sprocket-=29 on which is thechainBLconnected at one end `to th'e'carriage C andl providedJ with a weight 35 at vthe lother end whereby,` onith'e car beingduinped, the carriage islautomaticallyy pulled up theinclined tracks, bythe operation of the clutch 33. This clutchis operated by-means of a lever 36 Yconnected by aflever arm 37 and llinlz 38 to aflever'39 in4 turn connected to the clutch and'lhaving a trip iOfadapted `toy engage 'with the f can riage C' as itreaches the top of the-incline to automatically release the'clutc'h. lGn; the carriage going;y up the inclined tracks it pushes down a lever il weighted at 'its lower end so that as the carriage passes over itl theV upper'end will :engage the axle C1 of the carriage C as'mdlcated in dotted lines Figure l, thus locking the carriage at the ape-X of the incline. The inclination ofthe tracks 2l Fand 22v previously referred to ywill cause the car D "through, gravity to roll `off these tracks and ont'o the mine-return ltracks 57, and when: at a suitable distance from "the carriage C, the wheels D1 will engage and by the weight of the car D', pressa lever cable connected tothe bell'cranl42, causing the lever 4lv through the chainv 50y to` disengage from the aXlev C1; V

`When the carriage C' isreleased, it autoillustrated in Figure 1. In order however to prevent the carriage from dropping too quickly, brake means are provided in the form of longitudinally extending resilient bar members 171, which form part ofthe supporting vtraine 17", the end portions of the members 17l being cut away as indicated at 172 to permit the arm 173 to engage therewith.

rl`he arm 173 as indicated in Figure 1, is fixedly mounted on the shaft 4G., which is in turn rotatably mounted on the trame 17.

Securely mounted at the outer extremities oi the shaft 4;(3 are the lever arms e111 upon which are adjustably mounted the weight members/45. rIhe outward or inward movement of the weight-s on the lever arm 411 will increase or decrease the pressure ot the arms 17?', thereby automatically regulating braking power applied to the wheels of the car riage C through the. members 171.

The brake release comprises the lever V36 mounted on the shaft a9. rlhe lever 191 is also mounted on the shaft 49, and is connected by the chain a8 to the lever L1481, which is in turn mounted on the shaft L16. It will thus be observed that as the lever 36 is 0perated to throw in the clutch 33, pressure is released Yfrom the member 171 through the operation of the lever 119, chain 48, lever 481, and arm 173.

lVhen the car D comes from the mine loaded, it is pushed on to the rails 21 and 22, the weight of the loaded car being beyond the pivotal point 2O of the rails causes the car to tilt to an angle of approximately 45 as illustrated in dotted lines in Figure 3, the longitudinal members 51 supported by brackets 52 holding the car on the rails of the tiltable platform 18.

As the car tilts, the horizontal member connected to the trapeze member 2G engages the hooks 23 and 24, which are secured to the door 20, As the tilting angle increases the door 20' supported by the pivotally mounted arms 53 suspended by the hook members 23 and 24, is gradually drawn away from the end of the car, until as indicated by dotted lines in Figure 3, the door is held suspended clear of the car, permitting the ore or other content to slide out oi' the car. The lever 36 is then operated to bring the clutch 33 into operation.

Engagement of the clutch causes the carriage C to travel upward on the inclined tracks 12 and 13. It should be here noted that when the lever 86 is operated, that the car D is still in tilted or in dumped position` then as the Carriage travels upward, the chain 46a secured to the tiltable platform, and the base 10 respectively, and provided intermediately with a coil spring 5a, exerts a gradual pull on the raised end otl the platform, so that when the carriage C reaches the apex of the inclined trackway, the trip member l0 has 4disengaged the clutch 33, and the member Ll1 is in engagement with (he axle C1. The door 20 has been closed dur-4 ing the upward travel of the carriage and released from the horizontal bar ot the meniber 2G. The slight inclination to the horizontal ot' the tracks 21 and 2f? will cause the car- D to roll oit the tracks. operating the mechanism previously described,l when the carriage C will return to its normal loading position ready for the next operation. It. will be seen irom the. foregoing that the car D is taken from the mine on the lower track 5G and run onto the carriage C. which is normally in the position illustrated in Figure t3.

In this position the mine car is automatically dumped. Upon the completion of this operation, the clutch mechanism previously dcscribed, is then operated to elevate the car riage C which will upon reaching the apex of the. inclined trackway, automatically lock in elevated position, bringing the tracks Q1V and 22- of the carriage C into alignment with the upper mine track 57. rhe car D will then as previously described roll ott the tracks 21 and Q9 onto the track 57 to be returned to the mine, operatingl while liassing over the track 57, the release which allows the carriage C to return to normal lowered position.

As many changes could be made in the above construction and many apparently widely different embodiments ot my invention, within the scope ot' the claims, constructed without departing from the spirit or scope thereof, it is intended that all matter Contained in the accompanying specifica` tion and drawings shall be interpreted as illustrative and not in a limiting sense.
